批次轉換在你先定好規則再動檔案時效果最好。先決定哪些圖片需要調整尺寸、網站接受哪種格式、可接受的品質設定為何，以及檔案該怎麼命名。
可重複的批次計畫
- 備份原始圖片。
- 依用途分類檔案，例如主視覺、產品、縮圖或文章。
- 將每個群組調整為實用尺寸。
- 在支援時將交付副本轉換為 WebP。
- 只在必要處保留 JPG 或 PNG 備援檔。
- 替換所有圖片前，先測試幾個頁面。
ImgKit 的 Batch Image Converter 是可重複資料夾匯出的 Pro 流程。
先決定資料夾規則
良好的批次執行之所以可預測，是因為輸入在轉換前已分組。當需要不同尺寸時，請把主視覺圖片、產品圖庫圖片、縮圖、文章圖片與社群預覽放在不同資料夾。
匯出前使用簡單的規則表：
| 圖片群組 | 尺寸範例 | 最佳格式 | 命名規則 |
|---|---|---|---|
| 主視覺圖片 | 寬 1800-2400px | WebP 或 JPG | 描述性頁面名稱 |
| 產品圖庫 | 1200px 正方形 | WebP 加 JPG 備援 | 產品 SKU 與角度 |
| 部落格圖片 | 寬 1200-1600px | WebP | 文章 slug 與位置 |
| 縮圖 | 寬 400-800px | WebP | 上層項目 + 縮圖 |
先檢查小樣本
在處理完整目錄前，先用最終設定跑 5–10 個檔案。檢查檔案大小、視覺品質、透明，以及檔名是否仍與引用它們的頁面或產品記錄相符。
針對客戶交付或遷移工作，請保留一份記錄原始大小、輸出大小與節省量的報告。這能讓 QA 更輕鬆，也為下一位成員留下清楚變更紀錄。
常見問題
我可以直接批次轉換原始圖片嗎？
不行。請保持原始圖片不變，並為網站交付檔建立獨立的匯出資料夾。
批次轉換前應先決定什麼？
決定目標尺寸、輸出格式、品質、命名規則，以及哪些地方需要備援格式。
